Initial commit for UARTConnect module

* Keyboard interconnect using two uarts
* Supports daisy chain addressing using a master/slave direction communication scheme

- Still needs more testing
- Functions have been tested alone to be generally working

+# Example of 115200 Baud using a 48 MHz clock (mk20dx128vlf5)
+# 48 MHz / ( 16 * Baud ) = BDH/L
+# Baud: 115200 -> 48 MHz / ( 16 * 115200 ) = 26.0416667
